OK, I'll put the text there. I'll take a closer look later.

It took me a while to find out how to generate missing libraries for windows 
dll's on MinGW. And unfortunately no one didn't/couldn't tell me how to do 
it. I guess someone would be in the same situation. But, I assume future 
versions of MinGW will support the psapi.dll and dbghelp.dll.

I agree, do you have any suggestion?

Henrik.
